Families have spoken of their shock after a car - described as a "fireball" - rolled towards their apartment block in Halifax.
It's thought the handbrake cable burnt through, sending the car rolling towards the front door of the building, on Claremount Road.
The blaze was caught on camera by Saffron Pettinger and her partner Patrick as they tried to find an escape for their young family.
Police say they are not treating the fire as suspicious, and nobody was hurt.
